You’ll combine hands‑on infrastructure engineering and operational ownership with technical improvement and project delivery, gaining meaningful exposure to cloud technologies and our evolving hybrid cloud strategy.

The Role

Reporting to the Infrastructure Manager, you’ll support and develop the technology platforms behind Ridge’s UK operations.

You’ll own core infrastructure operations while delivering improvements, projects, hybrid cloud adoption and automation.

• Investigate complex technical issues, identify root causes and implement long‑term solutions.
• Contribute to hybrid cloud initiatives, helping modernise services and improve operational efficiency.

• Infrastructure standardisation and service improvement

Ridge’s diverse business offers exposure to varied technical challenges, requirements and projects.

Engineering, Delivery & Development

Alongside operational support, you’ll deliver infrastructure projects, drive improvements and help shape Ridge’s technology estate.

As you develop, you’ll gain greater ownership and build your technical and people leadership skills.

You Will:

• Lead or contribute to infrastructure projects from design and planning through to implementation and operational handover.
• Take ownership of technical workstreams, ensuring solutions are delivered to a high standard and aligned with business requirements.
• Contribute to infrastructure standards, engineering best practice and continuous service improvement initiatives.
• Act as a technical escalation point for complex infrastructure issues and provide guidance to colleagues where appropriate.
• Work closely with stakeholders, suppliers and project teams to support successful delivery of technology initiatives.
• Develop the technical leadership, stakeholder management and mentoring skills required for progression into more senior positions within the team.

This role offers technical growth, broader ownership and opportunities to shape Ridge’s infrastructure strategy.

About You

You’ll have experience improving business‑critical infrastructure in a complex environment, with strong technical skills, sound judgement and an ambition to grow.

• Strong practical experience supporting Windows Server environments, including Active Directory, Group Policy, DNS, DHCP and core Microsoft infrastructure services.
